I don't get why some SRs put their H/M count in bio, like 200+ H/M...If you always audit big names you will spend long time finding very few H/M, isn't it?


你俩能同框我是没想到的

Always great catching up with @VitalikButerin We got deep into how tech can inspire more people to live sustainably and mindfully.

Seeing Vitalik's tweet about GKR and wondering what it's all about? Good news: @electisec got you covered with a comprehensive guide! We've been publishing deep dive material on ZK from Reed-Solomon Codes to GKR to Virgo++ 🧠

这是真正的sbsecurity,致敬🫡

1 week and $250 - that was our 1st audit at @SBSecurity_ BUT It was never about the money. We wanted to learn. - How to provide max value - How to work with clients - How to lead a private audit You're in a similar spot? Don't chase money, chase experience. ✌️

Let's go Solana🤓

We just published another batch of tutorials on Solana development. It's over 40,000 words spread across 12 new tutorials. As usual, we go into extreme depth. Where it aids teaching, we visualize the layout of serialized data in accounts and walk through the core Rust source…

Will be attending the same events

Feel free to meetup if anyone is attending these events @ Shanghai next week :)

Wait, I found some new articles at rareskills.io/solana-tutorial 😁I found it before official announcement?

Summer 2022 - learn solidity as a hobby Early 2024 - learn rust for reading L1 code Summer 2024 - learn zk Now - evm at @electisec, move at @plainshift, and some solana request coming next Slowly but surely?

3 yrs ago - started learning Solidity as a hobby 2 yrs ago - joined Cyfrin, consistently produced great private audit output 10 months ago - started managing audit team, produced great business results turned audit team into efficient 💰 printer Now - living the dream 💪

Spent ~2 weeks on Solana confidential transfer zk contest, but didn't make it to the final leaderboard cause only top 3 qa reports get paid. A bit frustrating, but here is the evidence of me made it to top 7 at least😂

Amazing tool for large scale bug hunting 🫡🫡🫡

to those who want to find similar bugs in all smart contracts, in seconds. now available to all whitehats.



Grab my 🍿🍿🍿🍉🍉🍉 and enjoy the show🤣

Just to add more fuel to the fire: This “AI-found critical” issue was reported during a private @HackenProof contest, flagged as critical, and ofc closed as out of scope (contest was for critical-only). Yet somehow, @sherlockdefi got access to the same private codebase and…



Received @rektoff_xyz bootcamp graduation cert today! Thanks Rektoff for the amazing lectures, exercises, and of course the capstone. The bootcamp was a fantastic introduction to the Rust/Solana security world🙏

Not sure how sy::asset_to_sy() works. Is py_index similar to borrow index in Compound? I remember borrow index is a monotonically increasing accumulator used to compute interest and determine cToken value. I guess py_index is similar so inflating it causes price manipulation?

Nemo Protocol @nemoprotocol is a Pendle fork on Sui. On 9/7, it suffered a hack targeting the py_index manipulation, exploited for ~$4M. Here's the detailed analysis:👇
